Dima Pasechnik reports on sage-release]:
{{{
Builds and tests OK on Linux amd64 (Debian unstable). Got one test
failure:

File

line 1128:

that however would not repeat if I tested again...

I've also seen this error, on occasion. The test lines are
{{{
#!python
sage: import tempfile
sage: tmpdir = tempfile.mkdtemp()
sage: r.chdir(tmpdir)
sage: tmpdir in sageobj(r.getwd())
True
}}}
The script
{{{
#!python
import os
import tempfile
fail = 0
for i in xrange(1000):
tmpdir = tempfile.mkdtemp()
r.chdir(tmpdir)
if tmpdir not in sageobj(r.getwd()):
print tmpdir, r.getwd(), sageobj(r.getwd())
fail += 1
os.rmdir(tmpdir) # clean up
print fail
}}}
prints
